Install Security Baseline Kickstarter with Prowler

Introduction

The following demonstartes how to quickly install the resources necessary to perform a security baseline using Prowler. The speed is based on the prebuilt terraform module that can configure all the resources necessuary to run Prowler with the findings being sent to AWS Security Hub.

Install

Installing Prowler with Terraform is simple and can be completed in under 1 minute.

• Start AWS CloudShell

• Run the following commands to install Terraform and clone the Prowler git repo

  git clone https://github.com/singergs/prowler.git
  git fetch
  cd prowler
  git checkout -t origin/terraform-kickstarter
  sudo yum install -y yum-utils
  sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/AmazonLinux/hashicorp.repo
  sudo yum -y install terraform
  cd util/terraform-kickstarter
  

• Issue a terraform init

• Issue a terraform apply

  

  • It is likely an error will return related to the SecurityHub subscription. This appears to be Terraform related and you can validate the configuration by navigating to the SecurityHub console. Click Integreations and search for Prowler. Take noe of the green check where it says Accepting findings

  

Thats it! Install is now complete. The resources included a Cloudwatch event that will trigger the AWS Codebuild to run daily at 00:00 GMT. If you'd like to run an assessment after the deployment then simply navigate to the Codebuild console and start the job manually.
